... in the asphaltene composition from one region to another are anticipated due to the different maturation processes and the nature of the source. A comparison of elemental composition of asphaltene from worldwide sources indicates that the hydrogen to carbon ratio (H/C) varies over 0.05 1.15 %wt. On the other hand...

... a fully compositional wax deposition simulator. The wax deposition was modeled as a molecular diffusion process taking into account the effects of flow regime, adiabatic expansion, solubility effects and heat exchange with the surroundings. The fluid model was configured to match the measured wax...

... and compositional behaviour of topsides repressurisation from a multiphase system. The results were verified by comparison to slower, higher fidelity compositional modelling techniques, which illustrated good agreement for topsides minimum temperature and liquid carry-over predictions. High-level validation...

.... The fiscal allocation is based on these rates. The composition of the produced fluid varies with reservoir pressure. A base fluid is continuously fine-tuned to match the measured gas/condensate ratio at meter conditions. The gas and condensate flowrates, and densities of the export streams, are calculated...
